The invention discloses an induced electricity reducing device for a house around a power transmission and transformation facility. The induced electricity reducing device comprises metal wires and grounding wires fixed on wall surfaces or embedded among wall bricks. The induced electricity reducing device has the advantages that the metal wires on the wall surfaces form a shielding network covering the wall surfaces or roof of the house, the shielding network is in good contact with metal door and windows and metal door and window frames on the wall surfaces, and 4-6 positions, at the bottoms of walls, of the shielding network are grounded; meanwhile, grounding wires are guided from indoor large metal body positions such as a metal clothesline, and induced electricity can be avoided under a weather state in which induced electricity occurs densely.
